Problems solved by technology

[0002] In the injection molding process of many common daily necessities such as notebooks, the main purpose of the injection nut is to inject the nut into the plastic part, which can form an internal thread in the plastic part, which is convenient for installing and fixing other parts. The working method is to heat the nut and embed it. Insert it into the plastic part or directly use mold injection molding. During the injection molding process, the nut is hot-injected into the plastic and wrapped. After cooling, the plastic and the nut are bonded together. In order to ensure the firmness of the bond, there is a ring of embossing on the outside of the nut. After forming, the friction and occlusal force of the plastic and the nut are increased, while the existing embossed shape is a cylinder, the friction and occlusal force are insufficient, resulting in the weak joint between the plastic and the nut, which is easy to appear when fixing other parts Nut detachment phenomenon

Abstract

The invention discloses an anti-skid injection molding nut which comprises a nut body and an anti-skid net. The anti-skid net is arranged on the outer side of the nut body and is coaxial with the nut body, and the anti-skid net is connected with the nut body through a connection column. The anti-skid net is arranged on the periphery of the nut body, the anti-skid net and the nut body are fixed together through the connection column, through the structural characteristics of the anti-skid net, friction force and meshed force of plastics and the nut are greatly improved, connection firmness of the plastics and the nut is improved, and the nut disengaging phenomenon can not occur when other components are fixed.
